MULTIPLE PUNCHlNG-VIACHINE.

SPECIFICATION forming part of Letters Patent No. 741,180, dated October 13, 1903.

Application filed November 5, 1902- Serial No. 130,158. (No model.)

To @ZZ whom it' 77mg/ concern-f Be it known that I, JOHN S. STEVENSON, a citizen of the United States, residingr at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Multiple Punching- Machines, of which the following is a full, clear, and exact description, such as will euable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a front elevational view, broken for the purpose of better illustration. Fig. 2 is an end elevational View of the gap of a multiple punch, and Fig. 3 is a top plan View of one end of the punch.

This invention relates to a certain new and useful improvement in multiple punchingmachines.

The object of this invention is to produce a multiple punching-machine in which a portion of the punches are held in relatively fixed position and the companion punches are capable of longitudinal movement across a portion of the machine, the movement of punches at opposite sides being synchronized, so as to insure uniform spacing of the same from a fixed centralpoint, said parts being manually operative and adjusted to scales which determine the amount of movement thereof.

To that end the present invention consists of the features of construction and arrangement of parts, all as hereinafter fully described, and specically pointed out in the claims.

Referring to the drawings, A represents a broken portion of the frame ofa power-punch, only that portion thereof surrounding the gap being shown, as it is only that portion of the machine with which my invention coperates. B represents the lower portion of the frame, C the upper portion, and D the yokes at the ends, which yokes areintegral with the frame of the machine.

Resting upon thelowerportion of the frame are bed-blocks l, 2, and 3, the blocks 1 and 2 being movable longitudinally and the block 3 being held firmly in the central portion of the length of said bed portion of the frame. Ooiucidentwith said blocks 1, 2, and 3 and above the same are the slidable head-blocks 4, 5, and 6, respectively, which `are carried from the vertically-movable head-piece 7 by means of yokes ct o, secured to said headpiece,partly surrounding and supporting said blocks 4, 5, and 6, so as to permit shifting of said blocks on said head, to which head is imparted reciprocatory motion for the punching operation in the usual manner characteristic of this class of machines and being well understood will not be described in detail. Secured in like manner to the upper face of blocks 1, 2,-and 3 and the lower face of blocks 4, 5, and 6 are slidable blocks S and 9, which carry, respectively, the female members lO 4and the male members 11 of the punch proper,

and it is to secure proper positioningof these members that is sought by the present invention by manually-operated means characteristic of this machine, in contradistinction to power-operated devices in a self-contained machine in the application for patent for multiple punching-machine filed herewith. To that end the blocks 1 2 and 4 5 are provided on theirlovver and upper faces, respectively, With racks 12, with which racks mesh the pinions 13 14 and 15 16, which upon ro` tation in the direction of the arrows will cause the said blocks to move in a direction away from the central portion of the machine and when moved in the opposite direction will cause said blocks to move toward the center, carrying with them the punches in either or both directions.

As it is important that the male and female members of the punch shall be in exact coincidence to properly perform this function, it is important that when once setwhen one member is moved in either direction the opposing member shall be moved the same distancevin like direction. For that purpose I provide the hand-wheel 18 upon the shaft 19, held in the yoke 20, and with said shaft is carried the pinion 21, meshing with the gear ,22, which latter is secured to the shaft 23, provided at its upper and lower ends, respectively, with the bevel-gears 24 and 25,

ykeyed to said shaft and slidable thereon,

meshing with the corresponding bevel-gears 26 and 27, keyed to the shafts 28 and 29.

Upon the shaft 29 are two beveled pinions 30 ,and 3l, which have their beveled faces in opposite directions. The pinion 30 meshes with the pinion 32, keyed to the shaft 33, upon which is the pinion 34, meshing with the gear 35, which in turn meshes with the pinion 36, thereby causing pinions 32 and 36 to travel in the same direction, while pinion 36 is carried on the shaft 37, which has at its opposite or inner end the pinion 13, meshing with the rack 12 of block 1.

Near the upper end of the shaft 23 the pinion 24, meshing with pinion 26 and driving said shaft 28, gives rotary movement to the bevel-gear 40 on said shaft 28, which in turn meshes with the bevel-gear 41 upon the shaft 42, at the inner end of which is the pinion 15, meshing with the rack 12 on the upper face of the block 4.

Connected with the hand-wheel 18 is an inl Vdicating-pointer 43, which indicates upon the scale 44 the exact relative positions of the parts operated through said hand-wheel, the said scale and pointer being for the convenience of the person manipulating said hand-wheel, while the end blocks 1 and 2 are likewise provided with scales 45 and 46, so as to indicate from the front of the machine such relative positions also, thus serving as a safeguard against accidental displacement of the parts.

The description of the gearing herein applicable to the machine as located at one end is duplicated at the opposite end thereof, with this difference: The bevel driving-gears 30 and 4() at the left-hand end and the bevel driving-gears 3l and 47 at the right-hand end are reversed, thus causing opposite movement of all. their correlated parts, and while synchronizing the movement thereof such movement is imparted in the opposite direction, so that as the blocks 1 and 4 move toward or away from the central portion of the machine their corresponding blocks 2 and 5 Will also move toward or away from such central portion exactly the same distance, as will be indicated by the scales at the outer end of both blocks l and 2, during which movement the central blocks 3 and 6 remain lixed.

The particular application of the machine as invented by me has been to the punching of sheet-metal parts, such as sills used in the construction of metallic railway-cars, and it will be found 'especially applicable to that class of work or in any style of metallic structures in which precision of punching is required.

It will be apparent that the punches are capable of separate as well as simultaneous adjustment, which is readily accomplished by loosening the nuts 50 upon the bolts 51, the heads 52 of which travel in the longitudinal slots 53, whereby any single punch may be shifted to a new position upon its respective block. It will also be apparent that while I have only illustrated three punches, one of which is fixed and two movable, a larger number proportioned to the capacity of the machine may be used to advantage, some of which may be capable of movement longitudinally the bed ofthe machine and others held in relatively fixed position, or the whole series may be movable, if desired, all of which will be within the spirit of myinvention.

I am also aware that minor changes in the construction, arrangement, and combination of the several parts of my punching-machine may be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having'thus described my invention, what I claim, and desire to secure by Letters Patent, is-
